TYPE-CARRIER.

Specification of Letters Patent.

Patented Nov. 15,1921.

Application filed September 23, 1920. Serial No. 412,205.

To all whom it may concern:

Be it known that I, BELTON L. L'U'rz, citizen of the United States, residingat Reading,

in the county of Berks and State of Penn:

sylvania, have invented certain new and useful Improvements in Type-Carriers, of

, machines such as that disclosed by Patent No. 1,192,721, which was granted on July 25, 1916 to Nelson \Vhite.

One of these type carriers is ordinarily provided for each denomination or bank of keys and the type carriers are associated with the numeral wheels of the accumulator so that they will be automatically moved to bring the proper type member into printing position. The previous practice has been to provide each type member with'an. individual spring for normally holding it in a retracted position, and since there are ten type members upon each carrier and a separate carrier for each denomination, it will be understood that this requires a large number of small springs. Not only doesthe use of such a large number of small springs increase the cost of manufacture and assembling, but the springs are liable to' get out of order and'- close attention is required to keep the mechanism in operative condition.

One of the objects of the present invention has been to overcome this difficulty bythe provision of novel type retracting means in which a single spring member-serves to hold all of the type members upon one of the type carriers yieldably in a retracted position, thereby reducingthe cost of production and providing a construction which is more de-' pendable and less likely to get out of repair.

Further objects of the invention are to provide a device of this character which is comparatively simple and inexpensive in its construction, which can be easily assembled.

and taken apart, which is dependable in its 0 eration, and which is not liable to get out o repair.

With these and other objects in view the lnvention consists in certain combinations; arrangements and associations of the parts, as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a type carrier constructed in accordance with the invention, portions being broken away and shpwn in section to illustrate more clearly the details of construction.

designates the stock or body of the type carrier, said body-having an elongated formatlon, and being ordinarily mounted in a vertical position, as indicated by Fig. 9, so

that it can be moved up and down the necessary amount to bring the proper type memher 2 into position for printing upon a strip of paper rolled upon the platen l. The type carrier body which has been illustrated is similar in its general configuration to that used in the adding and listing machine dis- 'closedby Patent No. 1,192,721. which was granted to Nelson \Vhite on July 25, 1916. Longitudinal slots 3 are provided in the type carrier body and these slots are intended to engage fixed guide members so that the type fcarrier is properly directed in its up and receive the type members '2.

down reciprocating movements' The type members 2 are provided with printing faces 2 comprising the various numerals from to 9, inclusive, and all of the type members are normally held yieldably in a retracted position under normal conditions. As the type carrier is moved up and down by the mechanism of the calculating machine the printing faces of the various type members 2 are brought into operative position for printing against the platen. In the printing operation of the machine the type member 2 which is in operative position is struck by the hammer H and forcibly moved toward the .platen so as to make an impression upon the paper which is woundnpon the platen.

This operation is well known in the art and is illustrated diagrammatically by Fig. 9. After striking the type member the hammer is swung back into inoperative position and the type member again retracted'into its original position.

The upper end or head of the type carrier body is provided with side flanges 4 which are correspondingly notched at 5 to A retaining cap plate 6 fits over the type members so that the latter are confined between the retaining plate and the type carrier body and held slidably in position within the notches The retaining plate 6 may have longitudinal ribs 6 pressed; outwardly therefromin such a mannetas'to stifi'en the plate and reduce the frictional engagement between the plate and.-

the type members. The extremities of the retaining plate 6 are provided with end flanges 7 which are suitably notched at 8. to interlock with tongues 9 projecting longitudinally from the side flanges 4 of the typeearrier-body. Provision is thus made for securing the retaining plate in position by a' siiznplev interlocking connection and without the neeessityof usrng any separate fastening I members such as rivets or screws.

The type members 2 have the sides thereof which face toward the body I notched or cut.

away at 10 to provide a clearance space for the retracting bar 11, said bar extending longitudinally of the type carrier body 1 ind shoulders provided by the notches 116} of the type members: to Hold all" of the type members'2 in a retracted position ends thereof with laterally opening sockets 12 which loosely receive rounded heads 13 at the swinging ends of parallel levers 14. The two levers or arms 1-1 are similar and interchangeable and have the opposite ends thereof pivotally connected at 15 to the type carrier body. The type retracting bar 11 is thus mounted in such a manner that it is free to move laterally into a position parallel to itself, and the swinging arms 14 are arranged at a sharp angle to the retracting bar so that this lateral movement of the retracting bar will be accompanied by a minimum longitudinal movement thereof, thereby reducing the frictional engagement between theretracting bar and the shoulders of the type members.

One end of the type retracting bar 11 is provided with an eye 11 which is connected by a tension spring 16 to an arm 17 projecting from the type carrier. body 1, said arm and eye being bent or twisted so that the spring will be properly positioned to act freely without having a binding engagement with any part of the machine. This one tension spring 16, pulls longitudinally upon the type retracting bar 11 and operates to swing the same toward the rear edge of the type carrier body 1 so that the' type members 2 are all held in a retracted position. However, when any selected one of the type memhers is struck by the hammer H of the printing mechanism the particular type member is forced into a printing position, as indicated by Fig. 9; The type retracting'bar 11 will, of course, be moved with the type and is always held at substantialh' right angles to the type members. Those of the type members 2 which are not struck by the hammer 'lll- I'QIHEIIILHI a retracted position owing to their inertia and frictional engagement with the parts of the type carrier, although should any of these type members be shifted out of position no harm will be done, since as soon as the hammer H is moved back into inoperative position the type retracting bar 11 will be swung back to its original position by the spring 16, and all of the type members will then be held yieldably in retracted position.

i The parallel levers or arms 14: which carry the type retracting bar 11 are shown as provicled at the swinging ends thereof with stop arms 18 which are arranged to engage one of the side flanges 4e of the type carrier body and thereby limit the lateral movement of the type retracting bar 11 and the throw of the type members when struck by the hammer This mechanism eliminates the necessity of providing an individual spring for retracting each of, the type members, and not only is the cost of manufacturing the device greatly reduced, but there is less members carried thereby, of means including a single spring element for normally holding the type members yieldably in inoperative position, said type members being adapted to be brought individually into position to print.
